Hi to all, I found yesterday this species on a wet piece of wood in the wetland area. Size 0,5-2 mm diameters.
Spores 12-13 x 2-3 hyalin, smooth. Not blue reaction with KOH.
Any suggestion?

                Do you mean in iodine?
There is a Ionomidotis with such colour and spores but your spore size is too large and iodine reaction should be negative.

                Lugol is = IKI. If you have KOH (potassium hydroxide) or NaOH the you can test whether the ochraceous pigment turns out in the medium. My idea is perhaps wrong, but worth a test.

                Dear Zotto, 
Thank you for your suggestions and help. I'm really sorry, but I don't have the recommended reagents, such as the fungus is not able to present to me.

                To find a genus we need especially the excipulum, is it of globose cells or elongate, brown or hyaline. Also what paraphyses are between the asci?

                Dear Zotto, 
Thank you very much for your advice. Unfortunately, now I don't find more fruiting bodies. I wetted the piece of wood, and I hope, that I can find for the identification paraphyses , asci, etc.
